To use this driver you must have previously installed the PEAR package, also you need to install the Image_Graph package, and of course the cPdfWriter library above. You must install those first. These are some advantages of this driver over the PDFlib one included with Image Graph:

• Supports gradient fills
  (all types except MIRRORED which are translated to RADIAL)!

• Supports image fills
  (supports JPG, PNG(removes alpha) and GIF(removes transparency) formats)!

• Supports transparency
  (alpha-blending)!

• It’s LGPL so it’s free, even for commercial use :)!

Some examples from the Image_Graph website rendered with this driver (version 0.2!!!):
ver2-1.pdf, ver2-2.pdf, ver2-3.pdf, ver2-4.pdf, ver2-5.pdf

Notes:
To use this driver copy it in the Image_Canvas directory. This could be “/usr/share/pear/Image/Canvas/“ but it might differ for you. Then use it just as you would use any Image_Graph driver, i.e.:

include_once ‘Image/Graph.php’;
include_once ‘Image/Canvas.php’;
$Canvas =& Image_Canvas::factory(’CPDFWRITER’,
array(’width’ => 600,’height’ => 400));
$Graph =& Image_Graph::factory(’graph’, &$Canvas);
…

Enjoy!
